NASA will intentionally crash a plane for science today at 1 p.m. ET (1700 GMT). The space agency will also hold a 12:30 p.m. ET teleconference to discuss rising sea levels and climate change. You can watch the airplane crash webcast in the window below.
During NASA's airplane crash test, the space agncy will drop a Cessna 172 plane from a height of 100 feet to simulate "a severe but survivable" accident. NASA's Search and Rescue Mission Office will oversee the test, which is aimed at testing emergency locator transmitters, or ELTs. The test will be conducted at NASA's Langley Research Center in Hampton, Virginia, and will occur sometime between 1 p.m. and 2 p.m. ET (1700 and 1800 GMT).
"ELTs have to work in the extreme circumstances involved in an airplane crash. Included in those extreme circumstances are the possibilities of excessive vibration, fire and impact damage. NASA research is designed to find practical ways to improve ELT system performance and robustness, giving rescue workers the best chance of saving lives. This is the last of three crash tests of three different Cessna 172 aircraft. Each of the three tests simulate different, but common, crash conditions. The first plane was dropped from about 80 feet and came in at nose level on concrete. The second was hauled up to 100 feet and crashed nose down into soil, and the third is planned to come in from 100 feet, tail down, into soil."
At: 12:30 pm ET - NASA Teleconference on Rising Seas
At 12:30 p.m. ET (1630), NASA will host a teleconference to "discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will rise." You can listen to the teleconference live via NASA, or in a window below at conference time:
Speaking during today's telecon will be:
- Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington
- Steve Nerem, lead for NASA’s Sea Level Change Team at the University of Colorado in Boulder
- Josh Willis, oceanographer at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California
- Eric Rignot, glaciologist at the University of California, Irvine and JPL
